The fundamental characteristics of the estimated back-EMF, position and speed components using mathematical models of the IPMSM are analyzed. The analyzed sensorless control has back-EMF estimator, rotor position estimator such as a phase-lock-loop (PLL) type estimator, and disturbance observer. To improve the transient stability, the selection methods of major factors such as for sensorless control algorithm and the angle compensation method using a current feedback control are introduced.

A unified design and analysis framework for a class of observers is developed and the links between apparently different observer structures are brought out. Adaptive state observers equipped with a speed-adaptation law are shown to equal voltage-model-based flux observers equipped with a position-tracking phase-locked loop (PLL). The error signal driving the adaptation law or the PLL is presented in a generalized form. The developed framework enables revealing potential instability issues of existing observer designs and exploiting already existing stability results. A stabilizing gain design is reviewed and design guidelines are given. The observer design is experimentally evaluated using a 6.7-kW SyRM drive.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121217025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A least mean squares regression of the current samples is performed by an FPGA during the inverter's passive switching states to compute current slopes at active voltage vectors and evaluate them for position estimation. Using the predictive dead-time compensation as in [1], the inverter's nonlinearity effects are compensated with a high dynamic. The oversampling also creates a high signal-to-noise ratio in view of current measurement noise. Compared to [2], the novel approach of sensorless control is designed as a reduced observer in the estimated reference frame. This leads to high dynamics and a reduced parameter dependency. Experimental results show the high performance of the novel approach in closed loop sensorless control.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127861459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this kind of system, a main multilevel inverter (MLI) supplies the PMSM on one side, while an auxiliary two-level inverter (TLI) acts as active power filter on the other side of the machine. The MLI works at a low-switching frequency and high voltage while the TLI is pulse width modulated at low voltage. A sensorless high frequency injection method is adopted to detect the rotor position at low and zero-speed. The high frequency voltage injection is performed by the TLI in order to keep low and constant the MLI switching frequency, thus minimizing power losses. At high speed, the rotor position is instead detected by estimating the motor back-EMF. The proposed self-sensing approach gives both high efficiency and high control performance in all the operating speed range. Experimental results confirm the effectiveness of the self-sensing implementation.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"47 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133011769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since this structure is justified by the objective of obtaining low cost drives, a low computation burden sensorless method is proposed in order to further reduce the system complexity. A very simple algorithm for position/speed estimation coupled with a hybrid adaptive Phase-Locked Loop is indeed sufficient to achieve satisfactory results also in heavy transient operations. Furthermore, a novel control strategy is conceived with reference to an “equivalent” motor, whose rotor position is the average of the separately evaluated positions of the two PM motors. The proposed control technique is validated by an extensive numerical campaign.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126836423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At standstill and very low speed, the position is estimated by signal injection, while the rotor polarity is identified by a special process based on the estimation of the back electromotive force (back-emf) generated by small rotor motion. At high speed, the position is estimated by using a linear back-emf observer. Different observer gains are used at different speed ranges, such that the position estimate is reliable even at low speed. The combination of these two methods enables sensorless motor control in the full speed range including standstill. Experiments demonstrate the accuracy of the proposed estimation scheme.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134212463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This injection causes some unwanted side effects such as additional noise and torque oscillations, introduced by the harmonics of the current. This paper proposes an operating point dependent injection in combination with an arbitrary injection scheme in order to reduce these disturbances. It avoids, that more voltage is injected than needed during saturation, this results in reduced current and acoustic noise harmonics. The method includes an approach, how to define the injection amplitude in order to produce a measurable minimum high frequency current ripple. The method was developed with the aim to be easily implementable, without additional measurements and with less computational effort. The operating point dependent injection is verified by simulation and measurement results. For the illustration of the method a triangular shaped injection is used exemplary. The process is carried out for a reluctance synchronous machine.","PeriodicalId":386486,"journal":{"name":"2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129073567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
